Title: Frequency characteristic measuring device
Inventor: TANAKA YASUHIRO
IPC: G01R27/28
Filed: 1998-06-05
Abstract: PROBLEM TO BE SOLVED: To provide a frequency characteristic measuring device capable of enhancing measuring accuracy without lengthening the measuring time. SOLUTION: A frequency characteristic measuring device is approximately constituted by a high frequency generator; a measuring instrument; and a computer controlling the high frequency generator and the measuring instrument. Actually, the measuring device is a network analyzer or an impedance analyzer. In the case where a damping characteristic of a piezoelectric resonator is measured by using the frequency characteristic measuring device, the variation of a damping quantity is rapid in an area of frequencies f2-f3 and the variation of the damping quantity is loose in the area of frequencies f5-f6. Namely, since the most important portion of the damping characteristic is the area of the frequencies f2-f3, a measuring frequency step of the area of the frequency f2-f3 is reduced and measuring points are increased compared with conventional measuring points.  Since an accuracy of the area of frequencies f5-f6 may be low, the measuring frequency step is enlarged to decrease the measuring points as compared with conventional measuring points.

IPC: G06F13/00
Filed: 1989-06-19
Abstract: PURPOSE:To write a data in a transmission FIFO queue in high speed without disturbing the host processing by generating a transmission data without reading a data from an external memory with a memory access control section and inputting the data to the transmission FIFO queue. CONSTITUTION:In the case of receiving a command from a CPU section 1 via an internal data bus 10, an address control signal generating section 41 reads a transmission data from an external memory 7. The data read between the address control signal generating section 41 and the transmission FIFO queue 3 by means of a control signal (b) is written sequentially in the transmission FIFO queue 3. Thus, the address control signal generating section 41 reads the transmission data from the memory 7 one after another and writes the data into the transmission FIFO queue 3. Thus, the transmission data is written in the transmission FIFO queue 3 without reading the data from the external memory 7.

IPC: G06F12/08
Filed: 1997-05-30
Abstract: PROBLEM TO BE SOLVED: To optimize both performance and chip area by utilizing a cache memory with a built-in CPU core as a memory for storing a program and data. SOLUTION: This CPU core inputs external signals mode for instructing whether to use the cache memory 103 as a cache or to use it as a normal memory for storing the program and the data to a selector 108. When the external signals mode indicate that the cache memory 103 is to be used as the normal memory for storing the program and the data, an address decoder 105 decodes address signals outputted from a CPU main body 101, and in the case of matching with an address for which the normal memory is mapped, a timing control circuit 110 outputs control signals so as to access the cache memory 103 as the normal memory. Thus, the cache memory 103 is accessed as a high-speed memory.

Patent JP-H0447910-A (JP)
Title: Manufacture of metal foil clad laminated sheet
Inventor: WATANABE TADAO
IPC: B29K105/20
Filed: 1990-06-15
Abstract: PURPOSE:To prevent minute frictional scratches on the metal foil surface from developing and, at the same time, reduce warpage by a method wherein the difference between the thermal expansion coefficients of the metal foil and of a mirror plate is specified at the pressing of laminated materials, each of which is prepared by piling up the predetermined number of resin impregnated paper cloths and arranging metal foils. CONSTITUTION:Between the upper and the lower hot plates 4 of a press, laminated materials 3 and mirror plates 6 are alternately piled up under the condition that cushioning materials 5 are arranged so as to come into contact with the upper and the lower hot plates respectively. Each laminated material 3 consists of resin-impregnated paper cloths piled up one another and metal foils laminated to both the sides of said piled up cloths. The difference between the thermal expansion coefficients of the metal foil and of the metal mirror plate 6 is set to be 3x10<-6> or less. If somewhat friction develops, minute unevenness of the mirror plate surface or extraneous matter makes the cause for enlarging scratches. On the other hand, the nearest laminated sheet to the hot plate 4 is subjected to large bending force especially at cooling so as to be warped convex to the hot plate 4. Accordingly, by making the thermal expansion coefficient of the mirror plate 6 larger so as to approach to that of the metal foil, the expansion and contraction of the mirror plate 6 overcomes the bending force of the cushioning material 5, resulting in causing no strain to the laminated sheet and making the warpage of the laminated sheet smaller.

It is preferable that the composition ratio of mineral fibers of the upper and lower layer parts is 30-70 wt.%, the composition ratio of organic fibers of the intermediate layer part is 5-15 wt.%.  Thus, it is possible to obtain a wall structure which can be easily constructed, is excellent in fire protection and has high strength.

Abstract: PURPOSE:To provide a film having deodorization effect by forming a mixed layer containing catalyst for deodorization, a recessed and projected layer having a pattern like grains and spots, and a fluororesin layer on a black ceramic layer. CONSTITUTION:A ceramic layer D in which coating containing polytitanocarbosilane varnish and heat-resistant pigment which are main components is turned into ceramic is formed on a basic material E of a wall surface of a heating chamber. The coating in which fluororesin and for deodorization are mixed in the coating for undercoat film is applied on the ceramic layer D to form a mixed layer A. Zeolite, Mn, and Pt catalyst are added to the pigment having complex catalyst composition, i.e., compound oxides, in which adsorption material which adsorbs odor component and catalyst powder which decomposes oxidatively odor component are blended for black finish. A mixed layer B having a pattern like grains and spot is formed on it to make oil oozing due to food unnoticeable, and odor component is adsorbed and decomposed oxidatively by catalyst at the same time. A fluororesin layer C on it is finished in marble or thin film because adsorption and catalyst effect are reduced if the film becomes too thick.
